Jessica Simpson has joined the Instagram world and for her inaugural picture, she’s seen with her newly-engaged sister Ashlee Simpson and her new fiancé Evan Ross.

The mother of Maxwell Drew, 2, and Ace Knute, 6 months, posted on Twitter “It's official! I've just joined Instagram before it's not cool anymore!” with a link to her new account.

The first picture she posted was her cover of Redbook magazine but the second was a “family moment,” she wrote.

She also posted a photo of her daughter, Maxwell, writing “Love this lil lady more than anything!”

As we previously reported, Ashlee Simpson announced earlier this week that she was engaged to marry Diana Ross’ son Evan Ross.

Ashlee, 29, who has a 5-year-old son named Bronx with her ex-husband Pete Wentz, tweeted “My baby love and I are ENGAGED!!! Hallelujah Hawaii !!!!!”

Ross, 25, also tweeted “The love of my life said YES!!!!!!”

It looks like there could be two weddings this year in the Simpson family, as Jessica and her fiance Eric Johnson have confirmed they're done postponing their wedding plans after two surprise pregnancies. She's also been gearing up to slim down with Weight Watchers, which she's spokeswoman for.
